Be sure to tell the doctor.
Several suggestions.
Go through a head to toe stretching routine before bed, including your neck and face muscles (rotate head all the way one way then the other slowly with your shoulders pulling down to draw the muscles down. For the face muscles, make faces and feel the muscles pull and relax)
Get in a quiet routine before bed. No loud music, TV or other disruptive things.
Turn on white noise if need be ( a fan is good)
Be sure you have good support from bed and pillow.
Write things down before bed that you need to remember so you can forget about them.
Make the room as dark as possible to help you relax.
Can use warm wet wash cloth as compress on jaw.
Stay away from gum or other hard to chew items also things that can make you hyper, like sugar, or caffeine.
If your Doctor approves you can also try a sports mouth guard- be sure to ask first.
